1Z0-829 Controlling Program Flow Practice Question

This 1Z0-829 practice question tests your understanding of controlling program flow. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A method uses an enhanced for loop to iterate over a list of strings and prints each string. The code is:

```java List<String> list = List.of("A", "B", "C");

for (String s : list) {
    if (s.equals("B")) {

break;

}

System.out.print(s);

}

```

What is the result?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

A

The enhanced for loop iterates over the list, and when it encounters the string "B", the break statement immediately exits the loop. Therefore, only "A" is printed before the loop terminates. Option C is correct because the output is just "A".

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    The code throws a ConcurrentModificationException.

    Why it's wrong here

    The list is not modified during iteration.

  • ✗

    ABC

    Why it's wrong here

    Break prevents printing B and C.

  • ✓

    A

    Why this is correct

    Prints A, then breaks at B.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    AB

    Why it's wrong here

    Break occurs before printing B.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may think the break statement causes a ConcurrentModificationException or that it prints "AB" because they forget that break exits the loop before executing the print statement for the matched element.

Detailed technical explanation

How to think about this question

The enhanced for loop internally uses an Iterator, but the break statement simply exits the loop without calling any iterator methods. This is safe and does not trigger a ConcurrentModificationException, which only occurs if the collection is structurally modified (e.g., add or remove) during iteration. In real-world scenarios, using break to exit early is common when searching for a specific element, and understanding that it does not affect the iterator's fail-fast behavior is crucial.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A practitioner preparing for the 1Z0-829 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
